I'm on my third one in 75k. The last time I replaced it, I got the entire module. We'll see if it works any better. The newer module was all plastic instead of steel. There is also a procedure in one of the TDR issues, #28 I think, that explains how to fix your old one. But it only applies to certain versions. Mine was different than what they described.
